New Features in v4.3- Option to enable or disable the embedded register for Virtex-5 built-in common clock FIFO- ISE 10.1 support

Bug Fixes in v4.3(Xilinx Answer 29514) In the Verilog behavioral model, WR_DATA_COUNT behavior in asymmetric FWFT configurations is undefined - CR 449605(Xilinx Answer 29581) In the Verilog behavioral model, the behavior of programmable full is incorrectly defined for common Clock Shift RAM - CR 450727(Xilinx Answer 29513) In the VHDL behavioral model, the behavior of underflow flag during reset is undefined - CR 449899- In the VHDL behavioral model, DOUT is reset even when use_dout_reset is false. The work-around for pre-v4.3 cores is to use the Verilog or Structural model - CR 454156- In the GUI, Single Programmable Empty assert and Multiple Programmable Empty assert and negate max values are incorrect. The work-around for pre-v4.3 cores is for the user to limit the "Single Prog Empty" to a maximum of (Read Depth - 1), the "Multiple Prog Empty" Assert to a max of (Read Depth - 2), and the "Multiple Prog Empty" Negate to a max of (Read Depth - 1). - CR 448828
